I too use the one size fits all pliers to hold them when I tighten the screw. I don't use lock tight at all because I have had the screws stick and they are A pain to remove. So far never had one come loose but that could just be luck. A trick!!! Buy some cheap needel nose pliers, grind off the tip then drill A small hole in the tip big enough for the connectors shaft. Now you have A tool for installing them and it only cost A couple of bucks. I just made one up for A student today, 3 bucks!!
